Of all the "magical" products unveiled this year, the Sharpie Liquid Pencil ($2) might just deserve the praise if it lives up to its claims. The unique new writing tool uses liquid graphite to offer a writing experience similar to a pen, yet still allows for erasing mistakes. What's more, it becomes permanent like a Sharpie marker after about three days, making it a potential replacement for not two but three current inhabitants of your desktop pen cup.
